No. 690,584 11 Claims. (Cl. lill-19) This invention relates to machines for punching a record card, or other control record, with item coding ydesignations and printing the uncoded items upon the card to interpret the punched codal designations.

In general, the invention aims at a compact, rugged, simplified manually operable, portable record punching and printing machine of the kind in which parallel punch and type carriers are adjustable along 'columns of a record card to set their punches in differential item code positions and to bring corresponding item types, one of each carrier, to a printing line across the carriers. The invention features simpliiied imprint-effecting means including a platen movable to press the card against the types at the printing line to cause item printing on the card concomitantly with item code punching of the card. Means are provided by the invention to regulate the printing pressure applied by the platen. Manually operated drive means affording `large power advantage is used to actuate the punches and platen concomitantly. Also featured is detent means permitting free adjustment of the punch and type carriers until the drive means is brought into operation, whereupon the detent means is controlled to lock the carriers until punching and printing according to the locked carrier positions have been completed. Improved indexing means are provided for the carriers, and novel means are used to guide and feed an ink ribbon relative to the types at the printing line.

Other features and objects of the invention will appear from the following description and claims and be illustrated in the drawings which disclose an exemplary, specic embodiment of the invention.

In the drawings:

FIG. 2 is a section on line 2 2 of FIG. l.

FIG. 3 is a section on line 3 3 of FIG. 2.

FIG. 4 is a section on line `4 4 of FIG. 2, omitting the base and housing of the machine.

FIG. 5 shows the portion of the tabulating or record card punched and printed on by the present machine.

FIG. 6 is a section on line 6 6 of FIG. l.

FIG. 7 is an enlarged section on line 7 7 of FIG. 6.

FIG. `8 shows ribbon feed reversing linkage and is a section along line 8 8 of FIG. 6.

The illustrative machine is designed to punch a record card T (FIGS. 4 and 5) to designate items 0 to 9 according to the I-Iollerith code wherein a single perforation in a card column in one of its differential index positions to 9 represents or designates the corresponding digital item. In the present embodiment, square perforations are punched into card columns here arbitrarily numbered l to purely for convenience of the explanation. Concomi'tantly with the punching of item designations into the card, the uncoded items are printed at the top of the card to interpret the punched designations.

In detail, 10 is a base and 11 a housing for a framework with upright, opposite side frames 12 (FIGS. 2, 3, 4, 6 and 7). Confined between side frames l2 in smooth ilat-sided engagement with one another and with the side frames are ve like, elongated, parallel punch and type carriers P1 to PS. The carriers rest at on a somewhat forwardly inclined frame plate 13 bridging the side frames 12 and ride under a pair of spaced tie rods 3,036,518 Patented May 29, 1962 ICC 14. As thus arranged and mounted, the carriers P are capable of being individually, slidably moved lengthwise. Each carrier is constructed of upper and lower sections Consisting of bars riveted together at the rear and otherwise spaced apart to provide a card slot through which a record card may be inserted into work position. The card is guided into and supported in work position by means including two card holders 15 and 16 tixed to and extending outwardly from `the side frames 12. Each card holder has integral top side pieces paralleling the holder ybottom to form therewith a card pocket registering with the card slots in the carriers P. To place .a card in work position, it is inserted lengthwise through the ilared entrance of card holder 15, pushed through a slot in the adjacent side lframe 12, thence through the card slots of the carriers P and through the slot 12a in the opposite side frame and into the card holder 16 and against the stop pins 16a. Assisting in guiding the card into work position and in supporting the card is a front-grooved bar 17 across the side frames and in front of the carriers P. With the card in work position, its columns l to 5 are respectively centered within the card slots of carriers P1 to P5.

In the front end of its upper section, each carrier P slidably mounts a square-shanlied punch Ztl for movement across the card slot into a complementary square hole in a die 21 xed on the front end of the lower section of the carrier. Springs 22 urge the punches 2t) upwardly yagainst a common operating plate 23. Depression of plate 23 will force the punches of all yfive carriers down into `their complementary die holes to produce square perforations in index positions of the card columns correlated with the carriers. To the right of the punch 20, each carrier P is rigidly provided lengthwise along the bottom of its I upper section with a set of 0 to 9 types PT at index position spacing (FIG. 6). Opposite the sets of types of the respective carriers, their lower sections are formed with recesses Pa accommodating, with vertical play, an imprint eecting platen extending along a printing line across the carriers. The platen consists of a bar 25 topped by a rubber block 26 (see FIGS. 2, 4, 6 and 7). Bar 25 reaches outside the side frames 12 and has round tips iitting into the lower arms of `a pair of platen supporting levers 27, one outside each side frame. The levers 27 are formed with llat ledges 27a on which end portions of the bar 25 adjacent its round tips have Aflat seating to prevent rocking of the platen relative to the levers. Each lever 27 is pivoted `at 23 on a mounting plate 29 attached to the adjacent side frame and is biased to its shown counterclockwise position by a spring 39. With levers 27 in countercloclrwise position, they support the platen at the bottom of the recesses Pa in the carriers P. When the levers are rocked clockwise, they actuate the platen upwardly to apply printing pressure between the card, an ink ribbon, and the types, one of each carrier, along the printing line, causing the types to print at the top of the card columns correlated with the carriers. As shown in FIG. 4, the card guides 15 and 16 have cutouts above the end lportions of platen bar 25 to avoid interference with platen movement. The reentrant curvature of the lower arms of levers 2.7 is designed to enable them to skirt the right side of the card in work position and to support the platen within the carrier recesses Pa and beneath the card, in parallel disposition with the card and type faces for right-angular movement thereagainst so as to strike them with a flat blow during printing operation.

The punch and type carriers P are manually adjustable along the respectively correlated card columns by means of handles 32 riveted llush into sides of the upper sections of the carriers (see FIGS. 3, 6 and 7). The handles extend upwardly from the carriers and pass through elongated slots 11a in the top of the housing and through overlying slots 33a in an index plate 33 fastened to the housing by screws 34 (see also FIG. l). The ends of the handles are provided above the index plate with nger knobs PKl to PKS respectively related to carriers P1 to P5. Under the knobs, the handles mount pointers 35 for coacting with columns of digits (l to 9 marked at index position spacing on the index plate. The index plate is spaced `above the top of the housing suiiiciently to afford room for flat indicator strips 36 mounted on the handles 32 and marked at index position spacing with columns of digits 9 to 0 for selective exposure through a row of sight windows 33b in the index plate. When the operator is grasping a finger knob PK from a position in front of the machine to effect -adjustment of a carrier, the knob pointer 35 and associated column of digits afford a better, more visible guide to carrier adjustment. After all the carriers have been adjusted, the sight windows 33h and indicator strips 36 furnish an alined, more easily readable conventional indication of the carrier positions. In the example shown in the drawings, carriers Pi to P have been respectively adjusted to positions 9, 5, '2. 0 and 9. Adjustment of carrier P3, for instance, was effected by grasping the knob PK3 and bringing its pointer at 2 in the column of digits at the left, at which time the related indicator strip 36 brought its digit 2 into View at its sight window 33h. With carrier P3 adjusted to item position 2, its punch 20 is over the index position 2 of card column 3 and its item type PT-Z is at the printing line in printing position over the imprint-receiving area at the top of card column 3. Similarly, the adjustments of the other carriers P have diiferentially set their punches at selected item coding index positions of the correlated card `columns and have concurrently brought the corresponding item types to the common printing line.

Detent means are provided to center the punch and type carriers P in their chosen item positions; that is, to cent-er their punches 2t) over index positions to be perforated for codally designating the chosen items and to aline the corresponding item types, one of each carrier, along the printing line. The detent means include forwardly extending integral arms itl of the carrier handles 32 (FIGS. 3 and 6). Arms 4% ride on guide roller means f--l carried by a cross rod 42, Each arm is formed in its upper edge with V notches at index position spacing. f

Engaged with the notched edges of arms 4G `are ball detents 43 caged in the base of a bracket 44 fastened between side frarnes 12. Pressing upon the iive ball detents, one for each of the iive arms (il), are five downward bent lingers of a leaf spring 4S. Overlying the leaf spring is a straight rigid metal plate 46 having a similar configuration of five lingers clear above the downwardly bent leaf spring fingers. The leaf spring i5 and the plate 46 are commonly fastened by screws 47 to the right hand arm of a plate lever 48 pivoted on a cross rod 49 and bent down at the left end to follow a cam Sii fixed on a shaft 52. In the interest of compactness, the cam 5th is radially slotted to receive the front ends of the arms when the carriers P are in their foremost, 9 positions. Normally, the fingers of the leaf spring yieldably press the ball detents 43 into notches of `arms 40, permitting the teeth between the notches to ratchet freely past the detents during adjustment of the carriers. After completion of the adjustment and the insertion of -a card into work position, the operator depresses a handle 53 to rock the shaft 52 through its counterclockwise stroke. In the initial portion of this stroke, the cam 56 lifts the follower end of lever 48 onto the arcuate dwe-ll of the cam, rocking the lever clockwise to bring its rigid plate 46 down to the ball detents 43, thereby locking them in their thenengaged notches of the arms 40. The carriers P are thus locked and centered in their selected item positions and will remain locked until after punching and printing according to these positions have been completed and the shaft 52 has returned to home position, Note may be taken of the fact that the guide roller means 4l take the downward thrust of the locking plate 46 and, also, by their coaction with arms 46l help to guide the carriers P.

After causing locking of the carriers P in selected item positions, the shaft 52 drives means for effecting punching and printing according to the carrier positions. To the right of the shaft 52 is a parallel shaft 52', both shafts being mounted across the side frames l2 and reaching outside the side frames. Connected with the ends of shafts 52 and 52 outside each side frame is an identical force applying linkage comprising symmetrical front and rear toggles linked to each other by a bar 54. The front toggle has a link 55 dependently fixed to shaft 52 and hinged to a lower link 55 by a pin 57 also passing through the bar 54. The link 56 is provided at its lower end with a pin 58 extending inwardly of the adjacent side frame i2 through an elongated slot 59 therein. The rear toggle has a link 55 fixed to shaft 52', a link 56 hinged to link 5S by a pin 57 passing also through bar 54, and a pin Se at the lower end of the link 56 extending inwardly of the side frame through an elongated slot 59 therein. The relative disposition of the front and rear toggles and of the elements associated therewith is parallel to the inclined vdisposition of the carriers P, while the slots 59 and 59" are right-angular to said disposition and guide the pins 58 and S8 accordingly. The two pairs of pins 58 and 58 at the opposite sides of lthe framework engage in integral side lianges of the operating plate 23 for the punches 2t), suspending the plate at its four corners into parallel disposition with the carriers P. During the counterclockwise stroke of the handle-operated shaft 52, it straightens the front toggles which, through the linking bars 54, likewise straighten the rear toggles. As the toggles straighten out, ltheir pins 58 and 58 move down the guiding slots 59 and S9' and depress the plate 23 to drive the punches Ztl down into their complementary die holes to produce the item designating perforations in the card between the punches and dies.

Concomitantly with the punching operation, the platen supporting levers 27 are rocked clockwise b-y the symmetrical force-applying linkages to actuate the platen 25-26 through its printing stroke. Each linking bar 54 between the front and rear toggles of the force-applying linkages mounts an extension bar 60. The bar 54 has a pair of longitudinal slots 54a and 54!) (see FIG. 2). A shoulder screw 62 passes through the slot 54a into threaded engagement with bar 60' to clamp it hat against the bar 54. Projecting from the bar 60 is a pin 60a passing through the slot 54h in the bar 54. The bars 54 and 60 have right-angularly bent rear ends. Threaded through the bent end of bar 60 `and rotatably retained in the bent end of the bar 54 is a knurled-head screw 63. Turning of the screw 63 adjusts the bar 60 and its pin 60a longitudinally along the bar S4. The shoulder screw 62 is loosened before adjustment of the bar 60 is to be effected and is tightened after the adjustment has been made. The pin 60a on the extension bar 54 is in front of the radially extending upper tip of the platen supporting lever at the same side of the machine. When the toggles are straightened to depress the operating platel Z3 for the punches, the toggle linking bars 54 move to the right and the pins 60a strike the platen supporting levers 2'/ to move them through their clockwise stroke, causing the platen to apply printing pressure against the types PT alined along the printing line. The printing pressure applied by the platen depends on the extent of clockwise rocking of the levers 27 which, in turn, depends on the adjustment of the pins 60a.

In the above manner, punching of card volumns 1 to 5 (see FIG. 5) in accordance with the locked item positions of the carriers P and printing of the items at the top of these card columns are concomitantly eifected during the counterclockwise stroke of the shaft 52 produced by depression of the operating handle 53. In the illustrated example, with the carriers P1 to P5 set to item positions 9, 5, 2, 0 and 9, these items are printed at the top of card columns 1 to 5 and the corresponding codal designations are punched into index positions of the columns. After the punching and printing operations have been effected, the operator releases handle 53, permitting a spring 65 (FIG. 2) to restore the toggle linltages, punch-operating plate 23, shafts 52 and 52', and the operating handle to their home positions. The platen supporting levers 27 are restored by their springs 30. The locking means for the carriers P is restored under the influence of the fingers of the leaf spring 45, unlocking the carriers P for new adjustment.

The ink ribbon through which printed impressions are made on the card by types PT of the carriers P is designated R and is guided along the printing line between top and bottom leaves of a very thin ribbon shield 67 (FIGS. 4, 6 and 7). At its right side, the ribbon shield is cylindrically rolled to receive a shield-mounting pin 68 Xed at one end to one side of the frame, passing freely through the slots in the carriers P, and unattached at the opposite side of the frame, a washer on the unattached end serving to removably retain the shield on the pin. The bottom leaf of the ribbon shield is curved upwardly at the left (as viewed in FIG. 7) to insure passage of a card beneath the shield when the card is being inserted into work position. Registering openings in the top and bottom leaves of the ribbon shield expose the ribbon between the upper surface of the card and the live types, one of each carrier P, positioned `along the printing line. Under the areas of the card below the ribbon-exposing openings in the shield, the rubber platen block 26 has fiat-topped knobs to force these card areas firmly against the ribbon `and types during the printing operation. The ribbon is directed from the opposite ends of the shield 67 over spirally contorted guides 69 to ribbon spools 70. The guides are attached through their integral rear legs 69a to the mounting plates 29. Each guide 69 gradually twists the ribbon through about ninety degrees to take care of the angular relation between the shield 67 and' the ribbon spool 70 at the rear of the guide (see FIGS. 2 and 3). The spool is insertable upon the outer end of the reduced portion of a stud 71 extending from the adjacent mounting plate 29 and is retained on the stud by a pivoted latch 72 carried by the outer flange of the spool. Between the inner flange of the spool and the stud shoulder, the reduced portion of the stud rotatably mounts a ratchet wheel 73. Extending laterally from a side of the ratchet wheel is a pin 73a fitting into a collet formed on the inner ange of the ribbon spool to couple the spool and the ratchet wheel for common rotative movement. For each of the two ratchet wheels 73, one at each side of the frame, there are a feed pawl 74 and a holding pawl 75. The feed pawl is pivotally mounted at 76 on the adjacent platen supporting lever 27 and is urged toward the ratchet wheel by a spring 77 between the pawl and its mounting lever. The companion holding pawl 7S is pivoted on the adjacent mounting plate 29 and has a pin 75a extending laterally above the lower arm of the bifurcated right end of the feed pawl. With the feed pawl down in engagement with the ratchet wheel, it permits the companion holding pawl to be held down by its weight into engagement with the ratchet wheel to prevent its retrograde turning. When the feed pawl is raised out of engage-ment with the ratchet wheel, it acts upon the pin 75a to lift the companion holding pawl also out of engagement with the ratchet wheel. The engagement of the feed pawl 74 and, thereby, of the companion holding pawl 75 with the ratchet wheel 73 is under control of a lever 78 pivoted on the adjacent side frame 12. Lever 78 has a stud 78a at its lower end extending under the upper arm of the bifurcated end of the feed pawl 74. In forward position, shown in FIG. 2, of lever 7 8, it allows the feed pawl to be down in engagement with the ratchet Wheel. When the lever is rocked clockwise to rear position, its stud 73a lifts the feed pawl from the ratchet wheel.

As understood, there are two such levers 78, one for each of the two feed pawls 74 respectively located at opposite sides of the frame. The two levers 78 are cross-connected by a flat rocker bar 80 (also see FIG. 8) centrally pivoted by a shoulder screw 31 which holds the rocker bar down against the flat upper surface of a bar 82 bridging the side frames 12. The opposite ends of rocker bar 80 loosely extend into holes 78h in the upper arms of the levers 78. The lever 78 in FIG. 2 is longer than the other to protrude above the housing 11 (also see FIG. l) through an opening therein. When it is desired tol reverse ribbon feed, the operator uses the protruding end of the longer lever 73 to move the lever in a direction to reverse its position. Through the rocker bar 80, this causes the other lever 78 to be moved in the opposite direction into its alternate position. Thus, the two levers 78 are always set in relatively opposite positions, and when either of them is in forward position, then the other must be in rear position. When the platen supporting levers 27 are restored counterclockwise by springs 30 following printing operation, they move both feed pawls 74 to the left but only the one associated with the lever 78 in forward position is then engaged with and effective to turn its ratchet wheel 73. Hence, the ribbon spool coupled with the turned ratchet wheel is effective to wind up the ribbon and unwind it from the other ribbon spool. It should be noted that the shoulder screw 81 holds the rocker bar 30 down on the frame bar S2 with sufficient friction to prevent unwanted change in the positionV of the rocker bar and the associated levers 7S, without hindering the ability of the rocker bar to pivot about the screw when the operator is forcibly effecting a change in the position of the rocker :bar and lever arrangement.

While the novel features of the invention as applied to the shown embodiment have been pointed out, it will be understood that various omissions, substitutions and changes in the folrn and `details of the device illustrated may be made by those skilled in the art, without departing from the invention.
